Locate the main power module under the driver’s side dashboard to access all critical circuits. Each connector is labeled with amperage ratings and color codes for quick identification.
Check the secondary control panel in the engine compartment to monitor auxiliary circuits such as lighting, wipers, and climate controls. Loose terminals can cause intermittent failures and should be tightened to the manufacturer’s torque specifications.
Use a multimeter to test each circuit before replacing any overcurrent protector. Identify high-load lines like the infotainment system and power outlets, which are often linked to 15–20A circuits, and ensure continuity is intact.
Document all removed connectors and retain protective covers to prevent accidental shorts. Panels include integrated relays that may require labeled extraction tools to disengage without damaging clips or wires.

Access the primary control module beneath the dashboard to manage circuits for headlights, cabin lighting, and infotainment systems. Each terminal is clearly labeled with color codes and amperage, allowing quick identification of high-load lines and auxiliary systems. Regular inspection of connections helps prevent shorts and ensures consistent operation of all electronic components.
Review the secondary panel in the engine compartment for circuits controlling cooling fans, power outlets, and auxiliary relays. Use a multimeter to check continuity and voltage across terminals, and tighten loose connectors to maintain secure current flow. Maintain protective covers when reconnecting components to avoid accidental grounding or damage during maintenance.
Locating the Main Power Module and Circuit Layout
Access the primary electrical unit under the driver’s side dashboard to identify the key terminals controlling lighting, climate control, and infotainment systems. Labeling on the panel helps distinguish high-load circuits from auxiliary lines.
Inspect connections regularly for corrosion or loose terminals. Use a test light or multimeter to confirm proper voltage and continuity across each circuit before reconnecting components. Tightening fasteners prevents intermittent electrical faults.
In the engine compartment, locate the secondary power assembly near the battery. This section manages starter relays, cooling fans, and power outlets. Keep terminals clean and apply dielectric grease to prevent oxidation and voltage drop during high current demand.
Follow the color-coded wiring harnesses from the main unit to ensure accurate identification of circuits for diagnostics or upgrades. Trace each line to its destination before making modifications to avoid shorts or misrouting critical systems.
Document all changes to the module layout, including replaced connectors or added relays. Maintaining a record simplifies future maintenance and ensures consistent performance across electronic systems without accidental interference.
